3. Integration of GIS Web Services

Author

Paliulionis, Viktoras

Subjects
GIS, Web services, integration
Abstract

The number of GIS web services has been essentially increasing in recent years. The services encompass geospatial data providing and processing. GIS web services enable application developers to integrate GIS functionality into their web applications without having to build the functionality or host the mapping data locally. The integration of services from different providers enables creating more sophisticated services and applications. This paper analyzes peculiarities of GIS web services, and discusses ways of their integrating. In order to investigate issues of implementing distributed GIS web services, a prototype of a system was designed and implemented. The system integrates public map services and our specialized GIS Akis-WS services. This paper describes specific features and architecture of this system.

4. Ways to improve interactivity of internet GIS

Author

Abstract

The essential feature of Internet GIS is the interactivity between the users and the spatial data. Interactive GIS can offer interactive maps rather than static map images on the Web. Users can work with the maps interactively by performing conventionalGIS functions such as zoom, pan, search, etc. However, the interactivity of many InternetGIS is quite limited so far. In this paper, we propose to use AJAX to improve the interactivity of Internet GIS. AJAX design patterns that can be used to this aim are described in the paper. We present the architecture of the Internet GIS with AJAX-based user interface and integration with GIS web services.

13. Gis ir mobiliuju technologiju integravimo lokalizuotuju paslaugu sistemose ypatumai

Author

Paliulionis, Viktoras

Abstract

Lokalizuotuju paslaugu sistemos teikia informacija ir kitokias paslaugas naudodamos duomenis apie mobiliojo objekto arba vartotojo buvimo vieta. Ju paslaugos pasiekiamos mobiliaisiais telefonais, delniniais kompiuteriais ir kitais mobiliaisiais irenginiais. Lokalizuotosios paslaugos - tai pagalbos tarnybu paslaugos, mobilioji komercija, transporto priemoniu stebejimas, turizmo informacija ir kitu sriciu paslaugos. Darbo tikslas yra istirti lokalizuotuju paslaugu tipus, joms teikti taikomas geografines informacijos sistemu (GIS) ir mobiliasias informacines technologijas bei pasiulyti apibendrintaja tokiu sistemu architektura. Pateiktoji architektura grindziama klientotarnybines stoties modeliu, o baziniu paslaugu teikimo pagrindas yra GIS komponentas. Geografiniu duomenu vizualizavima tokiose sistemose nagrineja vadinamoji mobilioji kartografija. Jos ypatumai yra susije su mobiliuju irenginiu ribojimais (mazas ekrano dydis, maza skiriamoji geba, atminties ribojimai ir pan.) bei su zemelapio pateikimo dinamiskumo ir adaptyvumo reikalavimais. Mobiliosios kartografijos principams igyvendinti turetu glaudziau bendradarbiauti kartografai, GIS specialistai, mobiliuju informaciniu technologiju ir kitu sriciu specialistai.

14. Intelligent GIS: Architectural Issues and Implementation Methods

Author

Paliulionis, Viktoras

Abstract

The paper presents an intelligent GIS architecture that enables us to extend GIS functionality by using domain specific knowledge and inference engine. In this architecture, an intelligent agent monitors events, which occur in the GIS environment, and execute tasks depending on user's actions. The intelligent agent includes an expert system shell and knowledge base. A hybrid knowledge representation method is used that integrates rule-based, object-oriented, and procedural knowledge representations.
